Device

The present disclosure describes a controller add-on device configuredto add additional customizable buttons to a controller. FIG. 1 depicts abottom view of the controller add-on device. The controller add-ondevice comprises a housing 101 which is configured to couple tomechanically connect to the body of a controller. The housing alsoserves as a rigid attachment point for a plurality of buttons. Shown inFIG. 1 the add-on device comprises a right customizable button 102 and aleft customizable button 103 but the scope of the present disclosure isnot so limited. The plurality buttons 102, 103 are configured to bewithin reach of a user's index, middle or ring fingers while holding thebody of the game controller.

In some embodiments a portion of the housing 101 that includes thecustomizable buttons 102, 103 may be coupled to the housing by way of ahinged controller interface 201, seen in FIG. 2. Alternatively, thecustomizable buttons may be mechanically connected to the housing by wayof attachment to a switch mounted to a printed circuit board, theprinted circuit board coupled to the housing by, e.g., screws, pins,glue, plastic hot-stakes, clips, or housing elements. In someembodiments, the controller add-on may have a display screen 105. Thedisplay screen 105 may be coupled to the housing by way of rigidattachment means. The display screen may be associated with, e.g.,mechanically incorporated into, an input interface, e.g., a mechanicalbutton. Additionally the display screen may include user interfaceelements as touch screen, such as a capacitive touch screen or aresistive touch screen. In implementations where add-on includes thedisplay screen 105 and the buttons 102 103 and the input interface maybe configured to be within reach of a user's index, middle or ringfingers while holding the body of the game controller. In someimplementations, the input interface and/or buttons may be within reachof the user's thumbs, as well.

In other embodiments, display screen may be replaced by othercommunication elements such as a speaker connected to a printed circuitboard attached to the housing by rigid attachment means. In alternativeembodiments the user interface may feature a plurality of lights. Inadditional embodiments the user interface may comprise both a displayscreen and a speaker. In some embodiments the display screen isconnected to a printed circuit board attached to the housing by rigidattachment means. In other additional embodiments the speaker isattached to the housing by rigid attachment means.

FIG. 2 depicts a front view of the controller add-on device. As shownthe housing 101 provides a cavity, which is configured to fit acontroller body. A controller interface mount 201 is coupled to thehousing 101. The controller interface mount 201 may be rotatably coupledto the housing 101, e.g., by a hinge 104. The controller interface mount201 comprises one or more controller interfaces, e.g., an analoginterface 202 and a digital interface 203. These one or more controllerinterfaces are configured to communicatively couple the controller theplurality of buttons 102, 103 to the controller. Additionally, thecontroller interface mount 201 is configured to tilt with from a firstposition in which the add-on device can make a physical and mechanicalconnection with the body of the game controller to a second position inwhich a portion of the housing 101 conformally contacts the body of agame controller. The one or more controller interfaces may include,e.g., Serial connectors, Universal Serial Bus interfaces (USB), co-axialjack (co-ax), audio jack, S/PDIF connector, parallel connector and thelike. The housing may also have a conformal surface 204 located oppositethe surface having the buttons 102, 103. The conformal surface 204 isconfigured to make conformal contact with a controller body. Theconformal surface may include a pliable material to dampen vibrationfrom button presses as well as to provide a solid contact surface withthe controller body. The pliable material may be any suitable materialsuch as rubber, silicone, soft plastic, leather, and the like.

FIG. 3 depicts a side view of the controller add-on device. As can beseen, the one or more controller interfaces 202, 203 extend outward fromthe housing 101. The housing has a curved portion 301 to better conformto the shape of the controller when mounted. The curved portion 301 inconjunction with the tilting interface mount 201 also allows thecontroller add-on devices to be placed in a first position to makephysical and mechanical connection with the body of the controller,e.g., as depicted in FIG. 6, and then tilted to a second position tomake conformal contact with the body of the game controller, asdepicted, e.g., in FIG. 8. The curved arrow in FIG. 3 indicates thedirection of tilt of the interface mount 201 to go from the secondposition to the first position.

FIG. 4 depicts a back view of the controller add-on device. This viewshows an (optional) communication interface port 401. This communicationinterface port 401 may be used to relay signals from the controller toadditional devices such as headphones or other user interfaces. Thecommunication interface port may also receive signals from devices suchas microphones or other user interfaces and relay those signals back tothe controller. The communication interface port 401 may be of a similartype as the one or more communication interfaces 202, 203.

As seen in the top-down view of the controller add-on device in FIG. 5,one or more communication interfaces 202, 203 may be coupled to thehousing 101 so that the communication interfaces extend outward from thehousing over the conformal surface 204.

FIG. 6 depicts a side view of the orientation of the controller add-ondevice when initially coupled with a controller 501 (indicated by dashedlines). As shown, the tilting interface mount 201 allows the housing 101to be tilted downward relative to the controller 501 when the analoginterface 202 and the digital interface 203 connects to correspondinginterfaces 504 on the controller. In the depicted implementation, thehousing 101 is configured to fit securely between the two handholds 502of the controller and not interfere with the joysticks 503. Afterconnection is made, the tilting interface mount 201 allows the housing101 to tilt upward toward the controller 501 in the direction indicatedby the arrow so that the conformal surface 204 opposite the plurality ofbuttons 102, 103 can make conformal contact with the bottom of thecontroller. The curved arrow in the three-dimensional diagram of acontroller add-on device shown in FIG. 7 indicates the direction ofrelative movement of the tilting interface mount 201 as the devicerotates from the first position in which connection is made to thecontroller and the second position in which the conformal surface 204conforms to the bottom of the controller.

FIG. 8 depicts a bottom view of the controller add-on device whencoupled with a controller in the operational position. As shown, thecontroller add-on device is positioned between the two handholds of thecontrollers and the plurality of buttons 102, 103 on the controlleradd-on device are configured to be within reach of a user's index,middle or ring fingers while holding the body of the game controller.The housing 101 is configured to fit on a side of the controller bodyopposite the two joysticks 503 so that operation of the buttons does notaffect operation of the joysticks. The display screen 105 may beconfigured to face downward and be easily viewed when the controllerbody 503 is turned upside down. This can be advantageous when thedisplay screen has an associated input device, e.g., a button or touchinterface that can be operated by the user. While the depictedembodiment shows a display screen 105 mounted in the downward positionwhen the controller add-on device is couple to the controller body 503,the scope of this disclosure is not so limited. In other embodiments,the display screen may be configured face upward or frontward while thecontroller add-on device is coupled to the controller body.

Operation

The flow diagram of FIG. 9 illustrates a method for pre-set generationwith a controller add-on device according to aspects of the presentdisclosure. The method begins when a pre-set customization entry modeinput is received, as indicated at 901. The pre-set customization entrymode input may be a button press, a combination of button press or aselection using a touch screen. The pre-set customization entry modeallows users to map the plurality of buttons of the controller add-on tothe buttons or inputs of the controller. The pre-set customization modeallows button mappings to be saved as pre-sets and creates the abilityfor the user to easily switch between pre-sets when the controlleradd-on device is not in pre-set customization entry mode. Upon receivingpre-set customization entry, mode input the controller add-on deviceenters the pre-set customization entry mode 902. The user may beginmapping keys by selecting a controller button and choosing a button ofthe plurality buttons 102, 103 of the controller add-on to representthat controller button and provide that button's input when pressed. Thecontroller add-on device receives this mapping from the user, asindicated at 903. The mapping may be performed using a user interfacesuch as an input device incorporated into the display screen 105 or maybe performed using a separate program running on a host device such as agame console or a computer. The button mapping may be created, as apre-set in a list of pre-set, each pre-set in the list of pre-set may beblank before the user creates a button mapping or may be set to adefault button mapping that can be change easily by the user.Alternatively, new button mapping preset may be created by the user andadded to a list of pre-sets that may unpopulated.

Upon creation of a button mapping pre-set the user may select to exitthe pre-set customization entry mode. The user may take the necessaryaction to exit the pre-set customization mode, this action is receivedthe controller add-on device and subsequently the controller add-ondevice exits the pre-set customization entry mode 904. According toaspects of the present disclosure, the user may exit the pre-setcustomization mode by pressing an exit button or entering series ofbutton presses or selection an option within a user interface.Alternatively, the user may exit the pre-set customization mode byrefraining from pressing a button for a period. In some implementations,the exit button may be implemented using an input device, e.g., touchinterface or mechanical button associated with the display screen 105.

After exiting the pre-set customization entry mode, the controlleradd-on device saves the pre-set or presets entered by the user 905. Thepre-set or pre-sets entered by the user may be saved to a list ofpre-sets stored in the memory of the controller add-on device. A veryuseful feature of the present disclosure is that after the pre-setentered by the user to the list of pre-sets the device may hide orotherwise makes un-selectable pre-sets that are empty, invalid or chosento be hidden 906. This allows users to quickly switch between validpre-sets during operation of the controller add-on device, e.g., using abutton or touch interface that can be operated by the user. This mode ofoperation can be advantageous if the display screen and associated inputdevice face away from the user during operation. Reducing the availablemodes to a relatively small number, e.g., two, makes it easy for theuser to toggle between them without having to look at the screen.

FIG. 10 depicts the method for switching between pre-sets according toaspects of the present disclosure. During operation of the controller,add-on device the user may desire to switch between two or moredifferent presets on the preset list. To do this the user may press abutton or a series of button, or make a selection using a touch screen.The controller add-on device receives the pre-set change input from theuser 1001. Subsequently the controller add-on device selects the nextpre-set in the pre-set list and applies that configuration to theplurality buttons 1002. A feature of the present disclosure is where,the next pre-set in the pre-set list is blank, invalid or otherwisehidden, the controller add-on device will skip that pre-set in the listand select the next pre-set instead. Additionally the user interface ofthe controller add-on device will display the selected pre-set 1003.After selection of a button mapping pre-set a button, press by the useron one of the plurality of button 1004 triggers the pre-set buttonmapping. The pre-set button mapping sends a signal corresponding to thesignal of the mapped button in the selected pre-set to the controller1005. This signal is received by the controller, which interprets thesignal as a button press for the mapped button.

By way of example and not by way limitation a pre-set button mapping maymap an X-button of a game pad controller to the left button 102 and a0-button to the right button 103 of the controller add-on. When a userpresses the left button 102 of the controller add-on device, the devicesends a signal to the controller that the X-button has been pressed. Thecontroller interprets this signal as though the X-button on the game padcontroller has been pressed and communicates the X-button press signalto the game console.

As used herein, two objects, devices, or systems are “communicativelycoupled” when information can be transmitted from one object to a secondobject by way of some form of signal. By way of example the signal maybe an electric signal delivered through an electrically conductiveinterface, a mechanical signal delivered through a mechanical interface,an acoustic signal delivered through a sound-transmitting medium, or anelectromagnetic signal such as a radio signal, microwave signal or alight signal, which may be delivered through a medium, such as afiber-optic medium, a waveguide, or through free space. Communicativecoupling encompasses the use of intermediary objects, devices, andsystems such as transducers, transmitters, amplifiers, receivers, andsignal processers, e.g., digital signal processers.

Communicative coupling is a distinct concept from mechanical connection,though the two concepts are not mutually exclusive. As a non-limitingexample, communicative coupling via mechanical interface may between twoobjects be distinguished from mechanical connection of the two objects.For example, an actuating stud on one component may press a button on asecond object when the two objects are connected by means of screws. Thestud-button interaction provides mechanical communicative coupling,while the screws provide mechanical connection.
